Overview

KMPlaceholderTextView

A UITextView subclass that adds support for multiline placeholder written in Swift.

PlaceholderTextView

Usage

You can set the value of the placeholder property just like using UITextField.

Interface Builder

Storyboard

  1. Drag a UITextView object onto the canvas.
  2. In the Identity inspector, set the Custom Class name to KMPlaceholderTextView.
  3. In the Attributes inspector, you can change the value of the placeholder property directly.

Code

let placeholderTextView = KMPlaceholderTextView(frame: view.bounds)
placeholderTextView.placeholder = "What's on your mind?"
view.addSubview(placeholderTextView)

Installation

CocoaPods

You can install the latest release version of CocoaPods with the following command:

$ gem install cocoapods

Simply add the following line to your Podfile:

platform :ios, '8.0' 
use_frameworks!

target '<Your Target Name>' do
  pod 'KMPlaceholderTextView', '~> 1.4.0'
end

Then, run the following command:

$ pod install

If you are encountering the following warning when using Xcode 8, please make sure to set the Module in the identity inspector of your KMPlaceholderTextView in the interface builder to KMPlaceholderTextView as well:

warning: IB Designables: Using class UITextView for object with custom class because the class KMPlaceholderTextView does not exist

Comments
  • Fixes AutoLayout

    Fixes AutoLayout

    If the priority of the width constraint isn't reduced it is automatically broken. Running this without the priority lowered generates a string of warnings in the console log, meaning that this is being over constrained.

  • Layout fix: labels doesn't need constraints on booth sides.

    Layout fix: labels doesn't need constraints on booth sides.

    Labels requires only one horizontal and one vertical constraint. Try replace textview's bottom constraint with height constraint, and IB will generate warning. Removing tail and bottom constraints will fix that.

  • Rendering Performance

    Rendering Performance

    Hi The KMPlaceholderTextView won't give access to the UILabel used, so it's really difficult to setup the backgroundColor. Why do we care about it if it's transparent?. One of the slowest operations is rendering. In my case I'm using a lot of instances of KMPlaceholderTextView so if you use “Color Blended Layers" in the iPhone Simulator, you will see a lot of red areas.

    It would be really useful to have access to the background color of the UILabel - through a method- or the UILabel. Right now it's marked as private.

    Feature request: Separate fonts of placeholder and text?

    Other than color, it's very common to have a bolded or italic font for the placeholder, which is different from the regular text the user input. Can you add an option to set the placeholder font? thanks!

  • Has ambiguous scrollable content height

    Has ambiguous scrollable content height

    Thank you for useful pod!

    We have an issue using it in a storyboard. When adding a height constraint to the it Storyboard shows the warning: Has ambiguous scrollable content height.

    Is there a workaround for that? Or way to fix it?

    After investigation and StackOverflow research we think it's because IBDesignable KMPlaceholderTextView has placeholder subview, which UITextView UIScrollView probably takes as content and cause ambiguity.
